Planetary defenses MISSED asteroid flyby that came within 400km of Earth on Friday 13th — RT World News

A disturbing new record for the closest asteroid flyby of the Earth has been set, after a space rock named 2020 VT4 came within 400 kilometers (250 miles) of the planet on Friday the 13th. And our planetary defenses missed it.
The asteroid was spotted by the Asteroid Terrestrial-impact Last Alert System (ATLAS) survey at the Mauna Loa Observatory in Hawaii some 15 hours after it made its close approach from our sun-facing blind spot.

5-10 metres so half the diameter of Tunguska.

So if hit London the UK would cease to exist

Not extinction level but pretty noticeable.
